HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 793,130, dated June 27,1905.

Application filed November 22, 1904. Serial No. 233,853.

To (r /Z whom, it pmy (ZOIMJGT/b.

Be it known that I, FL'EMoN R. (Eh-inane, a citizen of the UnitedStates, residing at Ben tonville, in the county of Benton and State ofArkansas, have invented a new and useful Hay-Press, of which thefollowing is a specification.

This invention relates to hay-presses, and has for its object to producea device of this character of improved construction and increasedefficiency.

\Vith these and other objects in view, which will appear as the natureof the invention is better understood, the same consists in certainnovel features of construction, as hereinafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, andin which corre sponding parts are denoted by like designatingcharacters, is illustrated the preferred form of the embodiment of theinvention capable of carrying the same into practical operation, itbeing understood that the invention is not necessarily limited thereto,as various changes in the shape, proportions, and general assemblage ofthe parts may be resorted to without departing from the principle of theinvention or sacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a perspective view of ahay-press embodying the improved construction. Fig. 2 is a plan view,enlarged, of the plunger-operating portion of the device. Fig. 3 is aside elevation of the power end of the press with the plunger-operatingcam omitted. Fig. 4 is a transverse section on the line 1 4 of Fig. 2looking toward the plunger-operating cam.

The improved apparatus comprises the press-box 10, having thefeed-hopper 11, and with the bale-box 12 extending from one side andspaced base members 13 14. extending from the other side. The basemembers are connected at their free ends to a transverse sill member 15,suitably braced, as at 16, and provided with a buffer-spring 1'7,extending between the base members. Spaced guiderails 18 19 are alsoattached to the inner faces of the base members and preferably formed ofsections of L-bars, as shown in Fig. 4E.

The plunger 9, operating in the press-box 10, is of the usual form andprovided with the operating-beam 20, extending above the space betweenthe base members 13 11 and provided with a depending portion 21,projecting between the base members, and provided with spaced bars 2223, between which two rollers 24 25 are journaled upon a shaft theroller 24 having flanges .27 28 at the ends and extending over the uppersurface of the guidebars 18 19 and the other roller 25 operating betweenthe vertical webs of the guide members and beneath the horizontal websof the same,as clearlyshown in Fig. 4. By this means the beam will beguided in its reciprocal movement and maintained in position relative tothe base members, the lower flange 28 of the upper roller 21 riding uponthe upper faces of the horizontal webs of the guide members 18 19 andthe lower roller operating beneath said horizontal webs of the guidebars and between the vertical webs thereof, so that the beam will movewith the minimum of friction and will be prevented from either lateralor vertical displacement.

Attached to the sill member 15 is a standard 29, upon which an S-shapedcam member 30 is pivoted, and to this cam member the sweep" 32 isattached. ber alternately engages the roller 24. as the sweep is rotatedby the horse or horses connected to its free end, and thus produces therequisite reciprocal movement to the plunger in the press'box.

The beam 20 is provided with a retractingspring for returning the beamand plunger after release by the rotating cam, and the impact of therapid return stroke is received by the buffer-spring17and absorbedthereby and prevented from being imparted to the framework or otherparts.

The device is simple in construction, inexpensive to manufacture, strongand durable, and will operate efiiciently and with the minimum offriction and power.

Generally one horse will be suiiicient to operate the apparatus; but anynumber may be employed.

Having thus fully described the invention, what is claimed is- 1. In ahay-press, a press-box having pro- The S-cam memjecting spaced basemembers, a plunger for reciprocation-in said press-box, a plungerbeamhaving a portion depending between said base members and guided thereby,a roller mounted for rotation upon said beam and having lateral flangesextending above said base members and riding thereon, and a cam membermounted for rotation upon said base member and operative against saidroller between its flanges.

2. In a hay-press, the combination with a plunger-beam, of parallelbeams provided with inwardly-extending guide-webs, and rollers carriedby the plunger beam respectively above and below said guiding-webs forcontact with the corresponding faces thereof, and means for operatingthe plunger.

3. In a hay-press, the combination with a plunger-beam, of parallelguiding-beams havinginwardly-extending webs, upper and lower rollerscarried by the plunger-beam respectively above and below the plane ofsaid webs, and plunger-operating means having a cam for operation incontact with one of said rollers.

4. In a hay-press, the combination with a plunger-beam, of parallelguiding-beams havinginwardly-extending webs, upper and lower rollerscarried by the plunger-beam respectively above and below the plane ofsaid webs, the lower roller operating between said beams andapproximately fitting in the interval therebetween, and plungeroperating means having a cam for operation in contact with the upperroller.

5. In a hay-press, apress-box having spaced base members extendingtherefrom, a plunger, a plunger-beam having a portion depending betweensaid base members and guided thereby, straps connected to the free endof said beam and supporting a shaft between the straps, a roller mountedfor rotation upon said shaft and extending over said base members, aroller mounted for rotation upon said shaft and operating between saidbase members, and'a cam member mounted for rotation upon said basemembers and operatively engaging one of said rollers.

6; In a hay-press, apress-box having spaced base members provided withL-shaped guidebars, a plunger, a plunger-beam having a portion extendingbetween said base members, a roller mounted for rotation upon said beamand extending over the base members, a roller mounted for rotation uponsaid beam and extending between said base members and beneath thehorizontal webs of said guide-bars and a cam member mounted to operateagainst said first-named roller.

7 Inahay-press, apress-box having spaced base members provided withL-shaped guidebars, a plunger, a plunger-beam having a portion extendingbetween said-base members, a roller mounted for rotation upon said beamand extending over the base members, a retracting-spring connected tomaintain said beam yieldably in withdrawn position, a cam member tooperate against said roller, and a buffer-spring for receivingthe-impact of said beam when released by said cam.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
